Correct statement about sound wave

Click For Summary
SUMMARY

The correct statement regarding sound waves is that the speed of particles at the center of compression and the center of rarefaction is zero. This conclusion is based on the principle of Simple Harmonic Motion (SHM), where particle velocity is maximized at the equilibrium position, which corresponds to zero displacement. The teacher's assertion that the speed is maximum at these points is incorrect.

PREREQUISITES
  • Understanding of Simple Harmonic Motion (SHM)
  • Basic knowledge of sound wave properties
  • Familiarity with particle displacement and velocity concepts
  • Knowledge of wave mechanics terminology
NEXT STEPS
  • Study the principles of Simple Harmonic Motion (SHM) in detail
  • Research the relationship between particle displacement and velocity in sound waves
  • Explore the characteristics of sound waves and their propagation
  • Learn about wave mechanics and its applications in acoustics
USEFUL FOR

Students studying physics, educators teaching wave mechanics, and anyone interested in the properties of sound waves and their behavior in different mediums.

My answer is (1) and (2) but the teacher said it is only (1). I thought the speed of point at center of compression and center of rarefaction would be the maximum.

Or the correct one is the speed at center of compression and center of rarefaction would be zero?

Thanks

Your teacher is wrong. Each particle is undergoing SHM and so velocity is the greatest whenever displacement is zero.
